Arthur got to learn about the unique perspective of the NPCs as well as how they perceived players.
First, they found them strange and dangerous, having been through of mere myths. But soon enough, as the number of players increases and they become common, the NPCs would find them as normal as cabbages. In fact, they would learn about the advantages of the players too.
Any dangerous mission that could threaten the finite life of an NPC would preferably be given to a player who was an adventurer. Not just that, but the various gods and deities would also actively start showing their influence and affirming the position of the players.
Once the players got the approval of the various deities, it was the same as normalizing them for the NPCs forever.
"That's about all I know." The staff member finished speaking.
"Hmm… it's certainly accurate, I suppose." Arthur replied.
